If you throw a crop you grow or some kind of animal product into the
pond by the waterfall the Harvest Goddess will appear and thank you for
your gift.If you throw 5 items in she will give you a Power Berry. If you throw in 10 items you'll get an affection bonus with the girl who likes you the most. And if you throw in 20 items she'll give you a special kind of lumber that you automatically sell to Gotz for 1,000g.If you continue to give her gifts in this videogame she'll give you days with good weather.

If you throw cucumbers into the lake on the mountain where the Winter Mine is a Kappa will appear.It will only appear after 11:00 am during the spring.Kappas are creatures from Japanese mythology and they love Cucumbers.
If you throw 3 cucumbers into the lake the Kappa will give you a Mystic Berry.

The Hot Springs in this videogame are by far the best way to recover stamina and to restore fatigue. For every in game minute that you're inside the Hot Springs you'll recover 2 stamina and have 1 fatigue removed.You can stay up super late, jump in the Hot Springs for about an hour
at around 4:00 am, run back to your farm and be in bed before 6:00 am.
This will have a better effect on your stamina and fatigue than going to sleep at 6:00 pm and you'll be able to get a ton more work done each day.

On any sunny, non-festival day during the spring visit the Harvest Sprites
between 3:00 pm and 4:00 pm. Give them each a gift they love, Flour is
probably the easiest. You have to give them each an item without leaving
their house.
After you give them the gifts they'll invite you to their tea party.
At the end of the tea party they'll give you Relaxation Tea Leaves which
you can use to make Relaxation Tea.
If you submit Relaxation Tea for the Cooking Festival in this game you're pretty much guaranteed to win.

A lot of the characters in this videogame really love Spa-Boiled
Eggs. To get Spa-Boiled Eggs take regular or Gold Eggs to the back of
the Hot Springs and throw them in. You'll immediately receive a
Spa-Boiled Egg.
The screenshot shows exactly where to stand to throw the eggs into the Hot Springs.

After a hurricane happens in the game you can visit the beach where you'll find Kai. There will be an event where you get an affection bonus with Kai and you'll get a choice between receiving a bottle or Perfume.
To trigger the event you need to have at least 120 affection with Kai.
The bottle is useless but the Perfume makes a fantastic gift for the girls.

*If you give a jar of honey to Louis in this game he'll tell you the bees are of a rare species and the honey you collect will then sell for 60g instead of 50g.I realize the SUGDW Apple isn't in there because I wanted to keep my tables symmetrical. It sells for 50g like a regular Apple.
